The navigational satellite was expected to be launched on 12 June.
India's equivalent of the GPS will be called the Indian Regional Navigational Satellite System or IRNSS, a cluster of seven satellites being developed by the Indian Space Research Organisation ( ISRO) -- IRNSS- 1A, IRNSS- 1B, IRNSS- 1C, IRNSS- 1D, IRNSS- 1E, IRNSS- 1F and IRNSS- 1G.
The High Integrity GPS (iGPS) programme uses signals from both the Iridium low-earth orbit satellite constellation and the US Air Force-operated mid-earth orbit GPS navigational satellites. The iGPS combined constellations have the potential to provide positioning data to within centimetres.
Summary: SpectraTime, a company of the Orolia group (NYSE Alternext Paris - FR0010501015 - ALORO), today announced the award of a contract valued at approximately e1/44 million to supply Rubidium Space Clocks to the Indian Regional Navigational Satellite System (IRNSS).
Global navigational satellite systems (GNSSs) have a wide variety of applications, including positioning wireless devices, tracking during ionispheric scintillation, and determining the orbit of satellites, all of which involve weak signals.
The US Global Positioning System (GPS) is the most well-known navigational tool, but in addition to GPS there are at least two other navigational satellite systems to consider.
February 1982: Marecs-B, a marine navigational satellite, was disabled during a week of intense solar storms.
The DAK unit is a fiat dielectric ceramic patch antenna incorporating a rectangular microstrip configuration that is used to receive GPS clear/acquisition code (C/A) right-hand circular polarization waves transmitted by the 24 orbiting Navigational Satellite Timing and Ranging (NAVSTAR) satellites.
The Union Minister of State (Independent Charge) of the Ministry of Development of North Eastern Region (DoNER), MoS PMO, Personnel, Public Grievances & Pensions, Atomic Energy and Space, Dr Jitendra in a written reply to a question on the reasons for the failure of PSLV C-39 mission on the 31st August, 2017 said that the 41st flight of PSLV (PSLV-C39) that took place on August 31, 2017 with Indian Regional Navigational Satellite (IRNSS-1H weighing 1425 kg) could not reach the designated orbit, due to non-separation of Payload Fairing (also known as heat shield) during the 2nd stage of the flight.
The segment comprising mapping and navigation is projected to be the fastest-growing segment in the small satellite market as it helps the Global Navigational Satellite Systems (GNSS) to generate signals for effective navigation and accurate global positioning data during the forecast period.
The Indian Regional Navigational Satellite System (IRNSS) is a fleet of seven satellites intended to provide precise locations for civilian and defence purposes in India and 1,500km beyond the Indian borders.
The Indian Regional Navigation Satellite System-1A (IRNSS -1A), India's first navigational satellite, is set to be launched from Sriharikota spaceport at 1.01 am on 12 June, 2013.
